If you are currently learning a new language, then Duolingo might not be new to you. However, for the benefit of those who might not know, Duolingo is one of the most (if not the most) popular and widely used language-learning platforms.
Launched in 2012, Duolingo has become a leader in the language learning app sector. The platform offers language courses for learning purposes to over 500 million users worldwide!
The question you might be thinking is – 500 million users?! How did Duolingo become a go-to product when it comes to language learning for most individuals?
Well, the success of Duolingo can be largely attributed to its Product-Led Growth (PLG) strategy.
This case study delves into the tactics and methodologies.
Product-Led Growth (PLG) is a go-to-market strategy where the product itself serves as the primary driver of user acquisition, conversion and growth.
This approach focuses on creating a great product that solves a real need for customers; and then relying on the product to drive word-of-mouth referrals and organic growth.
It is a powerful strategy because current customers become advocates for the product, thereby helping to generate a growth loop of new users which will ultimately reduce customer acquisition costs for startups.
Duolingo’s product-led growth was based on 4 main ideas:
- Freemium model
- Personalized learning
- Social features and Viral loops
Duolingo adopted a freemium model where users could access the core product for free. With this, users have access to all the essential features needed for them to learn a new language
This low barrier to entry allowed for massive user signups and product adoption.
Another important product-led growth lever for Duolingo was the “gamification of the learning process”.
Duolingo gamified the learning process with daily streaks, XP (Experience Points), and in-app currency.
Additionally, Duolingo offers a variety of mini-challenges and badges for completing specific tasks or milestones, such as mastering a skill or reaching a certain level.
These features have made the app more fun and engaging, encouraging consistent use of the platform. As a user myself, I never want to miss a day because of this.
Duolingo’s personalized learning approach is built on the idea that learning a new language can be optimized for each individual, based on their prior knowledge, learning speed, and retention capacity.
Duolingo personalized learning by allowing users to set “Daily Goals” based on how much time they want to spend on the app daily.
Aside from that, Duolingo sends personalized notifications based on user activity. If a user hasn’t practised for a while, Duolingo might remind them about their daily streak or about a particular lesson they should revisit.
The goal is to make the learning experience more efficient and tailored to each person’s unique needs.
Social Features and Viral Loops
Duolingo has effectively leveraged a “viral loop” approach to grow its user base. A viral loop, in essence, is a mechanism whereby every user who joins or uses a platform can bring in at least one other user, leading to exponential growth.
They also included a social sharing feature that allows users to share achievements, and learning progress such as completing a level or maintaining a streak, on social media platforms.
All these things helped to contribute to Duolingo’s virality.
Here are notable results achieved by Duolingo’s adoption of a product-led strategy;
- Duolingo has over 500 million registered users and 42 million monthly active users.
- In July 2021, Duolingo became one of the few Ed-Tech companies that entered IPO (Initial Public Offering)
- Duolingo generated $250 million in revenue in 2021, and more than $265.7 million in revenue in the first three quarters of 2022, a 55% year-on-year increase.
By understanding their users, adopting gamification, personalizing user learning and social sharing, Duolingo not only achieved massive user adoption but also financial success.
Their product-led strategy is a good example of how a digital product can achieve exponential growth by focusing on user experience and leveraging the product itself as the primary growth driver.
